produces the outflow at the end of the pipe. This approximation method derived from Kalinin-Miljukov is identical to the linear storage cascade used for calculating runoff concentration. This means the flow ina transport reach can be simulated using a linear storage cascade consisting of [math]\displaystyle{ n }[/math] storages with the retention constant [math]\displaystyle{ K^* }[/math].
